Lane Departure Golf 7 : Rear Traffic Alert , Side Assist , Blind Spot Sensor

Driver Assist : Lane Departure with OPS Self Parking and Rear Traffic Assist

Retrofitted the new V4.0 Park Pilot/Park Assist on the Golf 7. A necessary tool for the spoiled driver like myself. 

There is a new Rear Traffic Assist function which works with the Lane Departure Assist. As described by Volkswagen here

The Rear Traffic Alert assists the driver, within the system’s limits, when reversing out of a parking space. Sensors in the rear bumper enable the system to monitor the lateral area behind the vehicle much earlier than the driver. If another vehicle is getting too close, an audible warning alerts the driver to the critical situation. If the driver fails to respond, the system can mitigate the potential consequences of an accident or prevent the accident in the best-case scenario by means of brake intervention where a collision is imminent.

The Rear Traffic Alert is available in combination with Blind Spot sensor or Side Assist.
Retrofitting the Lane Departure requires removal of the rear bumper to fit the sensors. The entire wing mirrors also need to be dismantled and broken down to run the connecting cable to the new mirror glass LED indicator. 

Installed the rear radar unit for the Lane Departure System

The mirror assy dismantled completely to run the additional wire set for the Lane Departure Warning LED on the mirror
During initial engine start up, the warning light would light
up as a checking procedure for the Lane Departure System

Additional control options on the HU 

Normal front OPS manual activation

The Rear Traffic Sensors reacting

The 360 deg sensor is a bonus plus to the rear camera.

Improvement have been made to the new Park Pilot Park Assist system V3.0 on the Golf 7. Unlike the V2.0 system found originally on my Passat B7, the newer system automatically triggers the display when in slow traffic situation or when in the car park around corners close to objects. This option can be controlled via the Discovery Pro screen.

RCD 330 340 G Plus Upgrading or MIB PQ Radio Upgrade ?

Upgrading Standard RCD510 RNS510 to RCD330 / RCD340 G Plus (downgrade) or MIB PQ upgrade ? 

Following the discontinuation of the RCD and RNS radios in 2014, Volkswagen have introduced the newer MIB/MIB2 PQ radio since 2015. This is a transition radio for all the PQ chassis models such as Polo, Jetta, Tiguan, Sharan and Passat. There are two models available in Singapore since 2015 on the Jetta, Tiguan and Sharan. 

Composition Media MIB for PQ cars ( single SD card slot )

Discover Media with Navigation MIB for PQ cars ( dual SD Card slots )

The App Connect feature on newer radio is a tempting option to upgrade from the old RCD 310 510 or RNS510 to the newer MIB radio which have this feature as standard. The USB/Aux connector is separately mounted compared to the Chinese RCD330/340. 

I find that the MIB radio are pretty neat. It react much faster than the old RCD/RNS radio that we have. The screen display is much brighter, sharper, clearer than the old LED screen of old. The radio icons can be selected to from your own jpeg files. 

One major disadvantage of the Discover Media which actually replaces RNS510, the DVD play have been deleted. In place, the App Connect suppose to allow you to play video or online video via the handphone using Mirror Link. This is hacked though. 

Currently, it is possible to retrofit these radio onto older vehicles which were using the RCD/RNS radios however the cost is a turn off. The MIB2 Discover Media is about S$2800 retrofitted whereas the Composition Media is about $2200. 

There is a cheaper option available from China. This is the RCD 330/340 radio. These are radios made for the Chinese markets. With some compromise, it can be used nevertheless.

Chinese market version PQ MIB with built-in BT, USB App Connect as one single unit

There is only one antenna input whereas VW cars here have two antennas. 

Firstly, the radio antenna has only one input but most VW cars here have the diversity antenna set up and have two antenna inputs. The supplier would provide a 2-into-1 adapter. The reception quality is not good in my opinion. The Volkswagen diversity antenna system does not work in that way when you join up the two into one. Another compromise needed.   

2 into 1 adapter

Vehicles using the RNS-510 already fitted with reverse cameras, would have to change the camera as well. The original camera for the RNS510 is a RGB type whereas the RCD-330/340 uses the RCA Video type.  The newer MQB cars are all using this set up. A change would be inevitable. 

The adapter cable for the new camera is usually supplied. 

Another observation is that the display on the Multi Function Display panel on the instrument cluster does not support the radio/media display unlike the older RCD300/510 RNS510 radios. The steering wheel controls works though. 

The Optical Parking System originally working on the RCD/RNS radios is fortunately, transferred to the RCD330/340 radio without any issues.  

If the vehicle is fitted with Dynaudio Sound System, it would not be possible to code the RCD 330/340 to support it as they are not available in the software of the radio. This would mean that there would be permanent errors on the Radio when diagnosed by the workshop ( all 4 speakers would be open circuit error ) . The sound level would be high as such, the radio volume needs to be set low during operation. The sound is amplified by the Dyaudio sound system no doubt. This have to be compromised. 

Be advised if you are proceeding with the change of the RCD 330/340 radio on your older VW cars from the RCD300/310 RCD510 or RNS510 radios.

Golf Mark 7.5 1.0 TSi Upgrade : Multi Function Steering Wheel

Upgrading Golf 7.5 Trendline with GTI Steering MFSW

Customer bought the newest Golf 7.5 1.0 TSi . A very basic car with the barest of equipment including a steering wheel with a horn button. There is a board computer which is controlled via the right side stalk for the wiper.

It is a Tornado Red Golf 7.5 which have a 3 cylinder 998 cc engine. Engine compartment look strange with the missing cylinder IMHO. Customer have obtained a fuel consumption figure of 20 km/litre. He upgraded the puny 205/50/R16 wheels to OZ Ultraleggera with 225/40R18. He is happy with the fuel consumption but claim that his friend obtained 25km/litre with the original set up. OMG ! 25 km/litre ? My Golf gave me at best 21km/litre on feather lite gas pedalling. 

Nevertheless, he wanted to upgrade his very plain steering to the GTI steering with RED thread. Very matching for his red Golf I have to agree. 

Gorgeous Red Golf 7.5 1.0 TSi  with the new headlights and DRL LED
Pity it did not come with the foggies. 

The new tail lights with LED but without the dynamic signal design

We managed to upgrade his steering to the GTI multi function type with cruise control and managed to upgrade his cluster from a simple board computer display to the multi function features. He can now see his radio/media details, phone data, car data, board computer data etc. The job took many hours due to the relative new car data available. 

GTI Steering with paddles, cruise control, audio/media control, phone and multi function control

Cluster upgraded with the Multi Function Display features controlled via new steering. 

End of the day, the customer was totally astonished by what he had obtain by a simple steering wheel change. We also deleted his Start/Stop feature which was pissing him off from the first day he got his car. 

Next project he have in mind....upgrade to Gesture Control 9.5" Discovery Pro2 with App Connect and Dynaudio ! Planning planning planning if his CFO approves it.

Changing TPMS Parameter

Changing Tire Pressure Monitoring System Parameter 

We changed the tire pressure monitoring system parameter firmware to adapt to the type of tires fitted on the vehicle. This is done by uploading a new parameter file into the #65 Tire Pressure module. 

Original Setting for Normal Load is 36 PSI Front and Rear

Original Load Setting Full Load is 39/46 PSI 

After uploading the parameter file, we changed the features on the MFD Cluster and Tire Load Limit display

Option to select Load and Tyre Type 

 We input only 17" and 18" tires option for the Passat B7

Followed the original 32 psi setting for Normal Load

Input the Full Load parameter as 36/41 psi

Passat B8 : Retrofitting Lane Assist and Adaptive Cruise Control

October 2017 : Passat B8 Retrofit Lane Assist and Adaptive Cruise Control 

The Passat B8 in Singapore is rather plain.  Given there is a R-Line version which looks pretty good but it lacks many features. Only the Exclusive 2.0 Passat B8 tend to be very well spec from factory. Unfortunately, there is hardly any Driver Assist features except Fatigue Alert and AFS Light. 

In Malaysia, the Passat B8 2.0 have the good fortune of having the Lane Assist fitted as standard. Unfortunately they omitted the Adaptive Cruise Control ACC.  A fellow Malaysian B8 owner asked why his Passat only show the parallel lines when he is in Drive Assist display. He was disappointed when I advised that the "car" icon display would only appear if ACC is fitted.

A local 2.0 Exclusive joined the Driver Assistance Pack Club recently.....

Removing the original windscreen under Kelvin's expert hands

Windscreen removed and surface prepared for the new screen

Amazing...the original screen was removed without any damages.
Anyone need a new windscreen ( used ) ?

New screen prepared for installation

Lane Assist Windscreen. 
Original harness need some extension to fit properly

New camera mounting housing 
Tell me the difference between the two emblems.

New ACC Sensor Protective Emblem

Instead of changing a new steering, the cheaper option is to change the buttons.

Believe me, removing this babe is not easy task. High risk in breakage if not careful. 

Finally, coding online for the new controllers....the system is working perfectly.

Picture taken by co-driver...the new set up of ACC and Front Assist/Lane Assist

No, the system is not cheap considering that a new windscreen needs to be used if the Lane Assist option is to be taken. 

And what the customer say at the end

Lowering Springs ; Aftermarket or Originals

Fitting Lowering Springs on the Golf 7 VII  : 25 Oct 2017

The Golf 7 is sitting rather high for a reason. Lots of travel and comfort comes with long tall springs but looks suffer and so does handling to a certain degree. 

I ventured into the world of lowering springs to achieve a better look and improved handling without too much compromise in the comfort department. 

What should I use ? There are numerous suppliers and vendors out there chanting that theirs is the best in handling, comfort and looks.  Notice that they usually have one or two part numbers to fit a variety of models. So much so, I think it would be a better bet to go along with Volkswagen engineering department which have spent extended effort to determine the best setup possible for their cars. The part numbers recommendation are confusing and there are too many part numbers to select from. 

Choosing the wrong set up or part number, you would end up with issues such as difficult handling, wrong stances, too low, too hight etc. This is an example of the complex setup

Actually, there is only one number applicable to a specific vehicle and this is tied to the vehicle's front and rear axle weight. So after a tedious study and research, I ordered a set of VW lowering springs.
I chose 5G4 071 677 B = MUB 071 675 + MUB 071 676 C = 930/890

Alot of springs  
Springs are from Mubea

Drastic Drop ! Front Springs

Rear Springs....also substantial

The shop fitted the springs in about 2 hours flat ! Pretty fast and skilled technicians from Godspeed ! 

Springs are so short, they did not have to compress them to fit the fronts

Conclusion : The ride have definitely improved. Firmer but yet not uncomfortably firm. Coupled with the Dynamic Chassis Control in Comfort mode, the ride is just nice for a Golf 7.
