TDI CRTD4 tuning box and engine warning RAIN

DriveS · 01-16-2018, 11:55 AM

I have the TDI CRTD4 tuning box fitted for 4 months now.

over this time on 3 occasions I have had the engine warning light come on then go off a day or so later. Each time I was driving in rain when this happened.

It may or not be the box thats causing this issue.

Anyone got the same box and had the same issue OR anyone get an engine warning light when driving in rain for a long period?

And - can you look at the fault codes in E-SYS ?

Silly question but have you checked all the leads and connections if they are or wet, also tried driving without the box in the rain?

Not a silly question.

Yes I checked the connections that were disturbed when fitting the box and also the box itself, which has a good sealing mechanism on it ('O' Ring).

Not driven it in the rain with the box off as it takes about 30 mins to remove so would need to be planned before the rain.... thats if it rains!!!
