Hello all, I'm hoping someone with more insight than me could provide me with some advice on an issue that is currently unfolding with my 2005 Golf 1.9 TDI BEW 5sp auto/tiptronic (09A I believe) with 135,100 miles. I recently had my timing belt and water pump replaced this past week and have begun to run into some issues upon warm starts. I will attempt to be as thorough as possible.
On a cold start, the engine turns over pretty much immediately and the car behaves in a normal fashion. My shifts are generally pleasant and acceleration is unproblamatic. Once the engine is completely warmed up, it continues to behave and shift like it should. Now say I stop the car to run into the store for 10 - 60 minutes, when I go to turn the car on it takes a considerable amount of cranking for the engine to turn over, around 3 - 4 seconds. When the engine does finally turn over the rpms shoot up to 2000 before dropping back down into idle around 800-900 rpms. When my car starts like this I know I am in trouble for the rest of the drive. The car over revs when shifting through every gear and this is generally accompanied by very harsh shifting. 1st to 2nd is rough, but 2nd to 3rd is the worst. The whole car jerks forward like I've just been rear ended. 3rd to 4th isn't pleasant and 4th to 5th is the smoothest, albiet still clunky. Trying to accelerate when my transmission is shifting like this is pretty hard and if I come to a stop at a red light, the car will idle at a rather noisy 1000 rpms. I have no check engine light and my OBD scanner is not picking up any codes.
I know my tranny has a 00300 code, which is the trans temp sensor I believe. Whenever my transmission has acted strange before, either switching into tiptronic or simply turning the car off and on again would fix the issue. This problem I have now seems to be exacerbated by turning the vehicle off and on again. Last time I attempted to resolve the issue this way, it appeared to make my shifting problems worse. My steering wheel would shake going from 1st to 2nd and placing the car in Drive would result in a delay followed by a very harsh and clunky engagement.
I'm really scratching my head here and am looking for any advice people may have. Any advice is greatly appreciated and I am happy to clarify any questions!
