I have a 1999 A4 2.8 manual w/ 121000 miles...


18010 - Power Supply Terminal 30 Voltage too low
17967 Throttle body (J338) fault in basic settings P1554-35-10 - intermittent
17953 Throttle valve controller:Malfunction P1545-35-00

This is what i got when scanned with a Vag scanner...
The car starts but dies right away...seems to be chocking...also makes a rattling sound that varies with the rpms of the engine ( could be something else though - not related to these codes)

Can anybody tell me exactly what these codes mean and what needs to be changed? It seems like the throttle body has gone bad...is it hard to replace? Does anyone have instructions on replacing one? Does a throttle body for an automatic the same or different than one for a manual?
Also my radiator fluid is leaking...Don't know from where. What is the best way to check where the leak is coming from?
Any input would be appreciated!

Also...would anyone have a used repair manual for 99 or similar years audi A4? I would be interested in purchasing one but don't want to spend the $70 or so on a new book or software.

 

The first code is for no voltage to the module. That may have made it lose its learned values for the throttle body. Try relearning the throttle using either vag com basic setting 60 or turning the key on for like 5 mins or so.
As for the leak, you may have to clean it and visually check leaks. Common places are the spots where the radiator meats the plastic side tanks and any place the radiator may be damaged from debris.

 

THanks - i found the leak - the water pump was broken/wobbly.

 

18010 is power loss. Either dicon battery or loose ground.

Clear it and see if returns. Do a TBA as suggested above.

17967 - TBA needed. Clear code.

17953- -Clear it, and check to see if it returns. If the codes return the throttle body control module or sensor may be bad.

70 dollars for a Bently isn't a cost. It is an investment that will save you hundreds.

 

What do u mean by TBA? Also what is the easiest way to clear the codes? I have tried disconnecting the battery for a while but the check engine light still remains. I don't know if returns because the problem is still there or if i'm just not clearing it. I don't have a scanner so I don't know if there are new codes or if they are the same ones that I had originaly.
