A lot of the throttle body info in here is quite old now.I was wondering if anyone has replaced or cleaned theirs in recent times and can shed any new light on the procedure.Ive got the PO2E fault code throttle valve stuck open so I want to clean or replace.I know the curved pipe is a bugger to get out and there's a bit of stripping down etc.Any new pitfalls or traps for the unwary that have come to light recently.Cheers guys n gals.

Tried throttle body cleaner via the intake pipe but hasn't worked.Difficult to see how to get the TB out as I can only get to it by feel and can only touch one of the bolts.Ive taken out battery , moved fusebox and coolant bottle to get access to pipe but can't get hand in any further.Anyone know what else can be moved to get access

Mine was took out and cleaned by a garage. But malfunction indicator came back on after a week. As error codes was saying it body throttle. 2011 diesel 2.2.

Stripped out everything to get to the TB today. Got as far as the elbow pipe. Hopefully release that tomorrow then I too can try to figure out how to unbolt the bloody thing.

The elbow connector has a bracket on it with two bolts so you've got to remove these first. After that, there's a locking clip you have to remove (anti-clockwise) which will let you take off the connector. Then you've got the four bolts that secure the throttle body onto the inlet manifold plus the electrical connector to disconnect.

Got the two bracket bolts off no issues. I can’t get the locking ring to move. It’s too far buried to get a decent visual and there’s no proper access from above or below to get a good push on it - very frustrating. Back at it tomorrow.

That ring gives people a lot of trouble. Have you seen this video showing the locking ring in a bit of detail - pity it's in Russian. I take it you're soaking it in WD40 or similar overnight.

Good idea! I was a bit reluctant to go straight in with WD40 but I think it’s the way forward. I’ve got to replace both lower suspension arms at the front, replace the rear windscreen washer pump and drop both upper and lower sumps off as well (oil leak) - so plenty to be getting on with if I get fed up with the TB task!

Going to have another go at it from the top.Will disconnect hose further back and try and remove the t body bolts by feel and take out the body and the nuisance pipe as one piece and remove pipe on the bench.I am satisfied that there’s no way to get at it from underneath.Anyone know where I can get a new gasket for the t body. it’s a 2014 2.2D .
