Had my thermostat replaced yesterday by a local VW Specialist. Also had my cam follower swapped at the same time.

As soon as I drove it again, it didn't feel quite right but this is my first GTI so didn't think too much of it as i have only driven it when the thermostat has been playing up.
It's almost as though the throttle wasn't smooth anymore. Without pushing my foot any higher or lower, the car would accelate by itself almost. It's quite hard to explain.

Anyway, heading to work this morning and the car decides to go into limp mode and pretty much shut down on me. Pull over,  restart etc. Take it very easy to work as its definitely not running right.
Scanned it with Vagcom this evening and I'm getting fault:

000568- Manifold Pressure/ Boost Sensor, signal too high.

As I tried to clear the code, the car tried to cut out on me. When it couldn't clear the code, it returned to "normal" again.

Can was running faultlessly before taking it to the garage yesterday.

Any ideas?

Thanks
Pete

Take it back to the garage  :happy2:

They've obviously cocked something up, so they should sort it out.

Think that fault indicates the MAP sensor. Maybe a dodgy connection or something.

MAP sensor needs checking, maybe some wiring got damaged?

Seems the sensor had slipped undone at the front of the engine. Back in, faults cleared and running like a dream again!

Thanks for the help all

I'm surprised they gave it back to you like that because when I did my thermostat and forgot to plug the MAP sensor back in, it ran like an absolute sack of sh1t immediately!

They probably just slipped the sensor on but it never clicked in fully because of the crud built up around it.

Then it can intermittently connect and disconnect.
