RS4: Fuel Questions & Answers

Hi,

I have a question about an error message I encountered on a predecessor to the current RS4, specifically the "old" Biturbo model (with a chip upgrade to 420 hp).

Error 16502: Coolant temperature sensor (G62) signal too high, intermittent, P0118-35-10.

Symptom: Intermittent hard jolting and misfires at full throttle The engine starts extremely poorly when it's lukewarm, and then revs up to very high RPMs (The error message and symptom seem to match.)

A friend of mine has this part and drives around with it despite this defect (which I think is quite unreasonable). His offer is unbeatable: I get to source and replace the sensor for him, and I get to drive it again.

Where is the sender located? Does anyone have the part number?

059 519 501A Double temperature sensor, 4-pin, green: €17.50 + "fairy tale tax" (likely a colloquial term for an additional charge).

If the installation location is the same as for the V6 gasoline engine (which it seems to be), I hope it has a thin arm.

Hi Smurfette,

What else can I say to such a great answer, other than: Thank you very much!!!

Hi,

Okay, so the donor part has been replaced, and the problem is gone. The tip about using thin fingers was spot on: Anything thicker than a pencil and shorter than a car antenna will wonderfully scratch up your fingers.

Here's the translation:

"However, the RS4 is still exhibiting the following issue: misfires in cylinder 6. Additionally, the knock sensor for cylinder 1 is still showing significantly different readings compared to the other 5 sensors."

Daher die Frage: Über jeder Zündkerze sitzt ein kleines Bosch-Elektronik-Modul mit einem 3-poligen Stecker. Welche Teilenummer hat das aktuelle Teil? Wie ist die Bezeichnung? WHow much does it cost?

Auf dem Luftfilterkasten sitzen 2 weitere Module. Welche Teilenummer haben die aktuell? Wie ist die Bezeichnung? What is the price?

Therefore, the question: Above each spark plug, there is a small Bosch electronic module with a 3-pin connector. What is the part number of the current part? What is its designation? How much does it cost?

That would be a common mistake.
spark ignition coil: 058 905 105 (note: there may be an "improved" version available): ~ €45.
Power amplifier: 4A0 905 351 A (possibly a later version): ~ €140 per piece.

Hi Smurfette,

Once again: Thank you very much.

If my friend gets back to me and I've seen his RS4, I'll let him know what's broken once I find out.
