Hi I wonder if anybody can help me after having throttle body issues on start up I googled cbzb throttle bodies .it came up with part no 03f133062b was compatible but the lucas lth505mf from the supplier is saying it is not the car starts and drives untill it idles for a 20 30 seconds then comes up with a p227900 tc air leak which it hasn't as fitted the original and has no problems at all .

Have you adapted the ECU to the replacement throttle body after fitting?

Do you mean throttle body aadaptions so yes

In that case let me know the VIN or reg so I can look up genuine part number for you.

TMBFN25J0E3066529 is the chassis no by the catalogue i have seen part no is 03f133062 so no b but when you google think b says is ok

Will look up in a sec, but if original TB is not giving faults, why are you replacing it?

Yep, correct part number for this car is 03F133062, not superseded by anything.

The esc light occasionally comes up when you start it tc p2100 fault code cleaned the throttle body still comes up car runs ok ,I turn of and restart vehicle is ok

Looked into cogs and they have worn

If it were me, I'd grab a secondhand genuine 03f133062, ideally from a lower milage car.

Ok thanks for your help

No problem. How many miles has the car done?

Just under 75000 had it from new serviced every year done everything needed on it

Hmm, our Roomster has same engine, same TB part number and 160k, and pretty sure it's on original TB.

Fault code suggests possible wiring fault, no?

The original throttle body comes up with p2100 tc on first start up and the new one comes up with p2279 only on idle both drive ok after a ignition recycle as the first one is so intermittent unable to do any tests to check
