Another post about the same MGF running too rich pig. Finally got fault code ,44, from it using snappi 'modus'. Launch couldn't talk to it. Snap On say this is a fault with the VVC unit. it gets stuck which leaves it either too rich or too lean. We got too rich!!!!!!!!!!

Has anyone had any experience of this? Is there a cure without spending out too much?

I know this is a very old thread but worth a reply as I come across it when searching for answers to the same error code. I was getting code 44 and 41 as well as oil temp wiring fault using snap on solus.

Car was running hugely rich, lumpy/poor idle but appeared to drive pretty much okay, lambda readings were way out.

Cat needed replacing as well as the lambda anyway so done that and it made no difference, after weeks of searching internet and testing all sensors I finally removed cam cover and discovered hydraulic vvc valve fully extended and stuck in that position, after carefully removing vvc valve I gently levered ram/piston control arm back up, replaced components and hey presto it idled perfectly and emissions returned to normal.

Turned out mot tester revved the car so hard during initial test it had jammed the control arm hence leaving the cams at full overlap on idle.

Hope this helps others.

Thanks - If I remember correctly (8 years ago - jeez, where has the time gone?) we did have that same fault - that was the last time I saw an MGF, luckily.

That was also when I wasn't such a well behaved member here and didn't post any fix. Shame on me.BigGrin


Bit of a predicament - with so many latching on to old threads - this time it was worth tho' it as it has now becomes a decent reference.

I agree with everything McTech has said but also you should have had a go at the MOT tester. On a petrol car he had no reason to rev it over 3,000 maximum!
