Top 10 1999 Volkswagen Passat Questions & Answers

Is the ABS light on as well? If you have ABS and the light is on (like in Guest's comment) is it probably the ABS Control Module. You should have someone read the code to see if you get ABS as one of the issues. Rather than spending a fortune with the dealer or having a non dealer replacement, check out ModuleMasters.com. You take the the unit off (easy and OK to drive without it, you'll just have no
ABS - which you probably don't have now!), mail it out to them, they rebuild it for $200, send it back and you install it, problem solved. They have step by step photo instructions on their site. A mechanic I use for diagnosis and difficult repairs initially wanted to replace the instrument cluster and then talked about replacing it with a new unit. I went online, read about the issue and fixed it myself. I let him know about it and now he has done it three times the same way with great results.

Passat 97 need to re-enter code ( 4 ) digit, however it shows the number 2 on the on screen when the radio is turned on.

VW Climatronic system works off and on when A/C refrigerant R134a quantity is low.
First of all you need to check & charge the A/C system with refrigerant R134a.
The A/C refrigerant R 134a quantity = 700 ... 750 grames.
This A/C failure is due to low refrigerant pressure & quantity.

Low pressure service connector

High pressure service connector

If the problem still occurs after A/C system refrigerant R134a has been charged, you need to access the Climatronic Module using suitable diagnostic equipment (VAS, VAG-Com, Bosch KTS, Texa, ...) connected to the data link connector of the car, in order to pull out all DTC's memored. DTC = Diagnostic Trouble Code. Then you will bu full informed about the root cause of the problem, and you will be able to repair & replace bad pieces and reset the Climatronic Module.
Let me know please about found DTC codes.

• Hi, I can help.

• This is a common problem with Passat's. I see you checked your fuses and relays so we will move on from that.

• You have a CCM Comfort Control Module in your car. This is a junction box of sorts that had the wiring for your electronics spidered through it. The placing of this was a real bad design because of it placement it gets water damage and the wires break etc.

• With the symptoms you are telling me I would bet this is your problem. It almost always is with the Passat.

• So now how to fix it. I know someone who did a fantastic write up on it with pictures and all. Here is the link http://www.headfuzz.co.uk/?q=vw_ccm

• If there is any water underneath or any hints of water having been around the are then the CCM might need to be replaced. Check for broken wires etc loose connectors etc.

• If you have any comments please feel free to leave them here and I will respond to you.
• Hope this helps and thank you for using FixYa.

ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.
For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.



ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.
The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.

If everything is in working order,then it is most likely a fog light harness plug for fog lights ,that where not an option on your car,the harness has just came loose from what held it up and secure.
