Hello all,
Just a hello, new to this place and seems to have a ton of good info. A little on me. I am a 15 year experanced tech that manages and runs a euro repair shop. I loved the tdi's because I have a few customers with over 300k and the car holds up as well as the engine. Yes its the little things that kill ya but I can deal with that. I was so impressed with the cars over time we got a 2000 jetta tdi for my wife. On average she does about 80-100 miles a day and its much more cost effective then her old car that got only 27 mpg (she holds a average of 47 mpg now in a lot of traffic with a lead foot!)

We have replaced the t belt some front end work and brakes all around. Have a driver door latch to be installed when I have the time but all common stuff in my world. Rocking 164K right now that's about 42k in the last year and a half!

I have a 91 gmc 2500 p/u with a 6.2 diesel. Its NA but hope to get a banks turbo kit for soon. Just a baby with 84K miles to date.

I am going to buy a mk4 golf tdi in the near fuiture to drive as a day to day car. The truck gets good mileage for a truck but its still a truck.

Only real prob with the jetta right now is the immo. Very random get a code 1176 (off hand I think its that ). I do my reading and searching and be posting my findings later on.

So for now a HELLO! and see ya soon.


Ps the jetta isn't stock. Well mostly but here it is
Egr disabled
Cleaned intake
Borla head lights
Upgraded clutch
No cat
Tweek pump timing
Fresh black paint job
20 precent tint all around

Well a 1176 error is

Immobilizer Reader Coil faulty.
Immobilizer Transponder in Key faulty OR incorrect Transponder in Key.

Remote Control:
Remote Control Battery low.
Remote Control faulty OR incorrect Remote Control used.

Check/Replace Remote Control.

Special Notes:
This Fault Code can be stored in due to Remote Control or Immobilizer Problems. On most Models these systems are separate and should therefor also be diagnosed separately.

In case of Engine Starting Issues please make sure that you are really experiencing an Immobilizer related Problem! On most models using conventional keys, the Engine will still start but cut out after 1-3 Seconds if an Immobilizer related Problem is the cause. On models using Kessy Systems and Electronic Keys, most systems in the car won't power up at all if if an Immobilizer related Problem is the cause. If you are NOT experiencing this behavior (e.g. Instrument Cluster powers up, and engine cranks but doesn't fire at all or engine won't crank) this is likely NOT Immobilizer related. When found in Audi A3 (8L), Audi A4 (8D), Audi A6 (4B) or Audi A8 (4D), check Wiring from Immobilizer Control Module to Immobilizer Reader Coil. A known issue would be the Length of the Wiring, an optimized Replacement Part may be available 8D0-972-275).
May be stored in Combination with 17656/P1248/004680 - Engine Start Blocked by Immobilizer in Engine Control Module.

The other one P1176 is Lambda correction after catalyst, bank 1 - control limit reached.;)
