Complaint:
Engine may be in limp-home mode and/or engine indicator lamp lights up, various fault codes present in area of exhaust gas recirculation (EGR system) or in charge air system.
Cause:
The exhaust gas recirculation cooling solenoid valve (Y27/13) sticks in the valve seat and fails to admit the vacuum
for the vacuum unit of the bypass flap.
This can cause sooting in the EGR or charge air tract.
Remedy:
Important:
•
Important: Only replace components which do not function correctly due to sooting.
•
In cases where the vehicle is under warranty please replace the affected parts.
•
In cases where the vehicle is no longer covered by warranty the components could be cleaned with a mild
aqueous cleaning solution.
1.
Check vacuum unit for bypass flap at EGR cooler for leaks (see 01.jpg).
Note: To do this, a vacuum of 600 mbar must be built up at the EGR cooler bypass flap vacuum unit using the
vacuum pump (W 001 589 73 21 00).
Specified values:
- The vacuum must be held for a period of 5 s and may drop by no more than max. 5 mbar.
Measurement results:
- If the results deviate from the specified values, the bypass flap vacuum unit must be replaced (see AR14.20D-7661SG).
- If the specified values are met/achieved, continue with the next step.
2.
Perform test of exhaust gas recirculation cooling solenoid valve (Y27/13) using diagnostic system.
Note: Use the diagnostic system for this.

Important: When the exhaust gas recirculation cooling solenoid valve (Y27/13) is actuated, the bypass flap vacuum unit and the linkage should move.
3.
If the linkage of the bypass flap vacuum unit does not move, replace the exhaust gas recirculation cooling solenoid valve (Y27/13).
4.
Connect diagnostic system and read out and erase fault memory (see AD00.00-D-2000-04SD).
5.
If the linkage of the bypass flap vacuum unit moves, check charge air system and exhaust gas recirculation system for leaks.
6.
If there are no leaks, please submit a PTSS case.
Note: The following information must be included with the PTSS case:
Diagnostic data:
- Quick test & Control unit log
- Fault freeze frame data
- Development data diagnosis sheet (DAS) or performance data acquisition (Xentry Diagnostics)
- Test logs: Dynamic EGR test, hot film MAF sensor, intake port shutoff (if present)
Vehicle data:
- Repair history
- Vehicle operating conditions: miles/day, freeway/urban/start-stop etc., customer's name
