Error Codes P1249 P2111 P1828 P1255 P2101 !


Recommended Posts


Just had a leaking gearbox fixed and engine loom repaired and now I get these error messages! I swear the car is costing me an arm and a leg.

Has anyone experienced any of these codes and found the cause:

P1249 Boost Pressure Control

P2111 Throttle Actuator Control System stuck open

P1828 Pressure Control Valve

P1255 Boost Pressure Curve, Upper value exceeded

P2101 Throttle actuator control motor circuit range/performance

00801 High Press. Switch coupling.

I have already done a search and the brilliant Loren came up with

P1255 Boost Pressure Characteristic, Upper Value Exceeded - Above Limit

Possible fault cause

- Leakage at pressure hoses from frequency valve to the bypass flaps

- Frequency valve faulty

- Vacuum modulators for bypass flaps leaking

- Bypass flaps incorrectly adjusted

But what about the others? I have been told a single fault can create multiple error messages.

Strange thing is that when I drive no PCM ABS lights come on. The light only comes on at 90 mph with my foot down.

When I stop the car turn off ignition and restart the car the lights go out and everything is fine. Foot down upto 70-90+ mph not a problem.

Any advice greatfully appreciated. Everyone speaks so highly of a 996 turbo but this one is proving to be a bit of a ball ache :huh:

Sounds like things were not put back right.

I would take it back and tell them you did not have these problems before their repair.

I would but I dont trust him anymore. He was a nightmare to deal with. :angry:

Seeing these errors do you think there is multiple problems???

I was told that a single problem can cause these error messages?

hi, you may check the connector from the tiptronic transm (lifting the car).

it has connection to the e-gas , ecu ....... :)

also leak in the turbo charging sistem could cause these strange problems. you could check your boost on third gear with 3000 rpm ---> ;)

good luck
