Help!!!! A4 B5 1.9 TDI VAG COM error code 01237

Hello,

I've recently been experiencing a problem where the car briefly and automatically increases the fuel supply upon starting, and then returns to idle. Performance is no longer optimal. The vehicle can only reach a maximum speed of 140 km/h.

When I read error codes using VAG-COM, the following appears:

Code:

Control Module Part Number: 028 906 021 GN Component and/or Version: 1.9L R4 EDC G00SG 1422 Software Coding: 00002 Workshop Code: WSC 06325 1 Fault Found: 01237 - Fuel Shut Off Valve (N109) 04-00 - Mechanical Malfunction

as an error message, I deleted it, but it keeps coming back.

what can I do there?

I have an Audi A4 B5 1.9 TDI with engine code AFN, manufactured in 1997.

PS. I've been searching extensively on Google and found a R109, but I don't have a relay for it.

Many thanks in advance

The fault memory already says so. The fuel shut-off valve will be defective. It is possible that they get stuck, and then an error occurs.

Use the forum search for fuel shut-off valve. The relay 109 has a different number in the B5. Search for relay 109 and Audi, there should be a thread there.
