Error code 28????

[ChopperTVR]

Any ideas on this error code. It doesnt stay on. It occasional and sometimes the digital screen gies red, the blank then back to normal.
Just drove back from derby after collecting her so a good 165 miles with no effect on performance or feel??????
Gotta love a TVR.
Best money I spent today and great weather!!

Code 28 air con fault

Air con!
Thanks, will get her down the garage.
Well I feel a bit better it's only that!
Sure it will be something else next week.

[ChopperTVR]

But pretty pointless when its hot the roof comes off.
Just something else to go wrong!

No 28 in there.
I can't seem to get the codes on line. Where did you get those?
Thanks

[nrick]

28 isn't there for some reason but reported as an aircon fault.

[ChopperTVR]

Thanks for the help all
