V40: Throttle Body problem

[Johnt71]

I have a 1.8 GDI engined V40. It has done 126K miles and developed a 'misfire' which meant the car went into protection mode 1500 rpm max, until the engine was cycled off and on again.
The garage have said the stepper motor is out of calibration and a new throttle body is required. We had one fitted only 3 years ago.
The engine is coked up, which I know is normal for these engines.

My question is there a common issue with the throttle bodies and is there a cheaper fix?

Any advice gratefully received.

I have the exact same problem my vehicle is an x plate s40 gdi 125000 miles developed misfire cylinder 1 wont tick over have swopped coils plugs only code is p0300 p1221 and po141
the battery has been flat for a while charged it up and took it for mot now have this fault.
I have after 2 days checked wiring back to ECU for coils and these are ok i am now suspecting the ECU
Any ideas are welcome please.

My misfires were caused by a failed coil. Hard to find I'm afraid, try you local scrapyards for either a Charisma of S40 GDI 1.8. If you find one, take the throttle body too, taking care to make sure it's the right one for your age of car. If you don't mind spending more for a coil, quite a few on ebay, normally go for about 25-30 quid.

If you're desperate, people break cars on ebay, I got a throttle body for £40 delivered by just ringing people who had entire cars.

My coil and throttle body failed at about 125k too! When the throttle body went, I was 200 miles from home and had to spend 400 quid to get towed back! Thankfully, I claimed it all back

Hi thanks for the quick reply i am going to take it to my local Volvo garage i have asked him about the codes but he says his software is the proper Volo kit as the Snap On codes dont mean anything to him.
Thanks.
