raddys Posted December 1, 2020 Share Posted December 1, 2020 Hi guys My car had a heater matrix leak and coolant leaked all over my ecu, the heater matrix job is now done but my car is now not boosting correctly and sometimes hunts up and down on the boost gauge, sometimes it comes on boost fine but most of the time you floor it and its like flooring an n/a. Its back in the garage and they have checked all turbo pipes etc and next step is testing a different ecu as we think that may be the problem. If a new ecu doesn't work I suppose il have to find a way to check the vsv's So my question is, does anyone have one for sale? Many thanks, Grant Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted December 1, 2020 Share Posted December 1, 2020 Id check the VSVs before the ECU Quote Link to comment Share on other sites More sharing options...
raddys Posted December 1, 2020 Author Share Posted December 1, 2020 Problem is the car had no problems until it went into the 1st garage (they put an old seal on the new heater matrix and on 1st start up it pissed everywhere, covering the ecu, previous leak was just a trickle) So I doubt it is the vsv's, it would be to much of a coincidence that as soon as coolant passes on the ecu that the vsv fails at the same time Quote Link to comment Share on other sites More sharing options...
raddys Posted December 1, 2020 Author Share Posted December 1, 2020 Is there a quick way to check the vsvs?, the garage think it could be an hour or it could be very labour intensive if they have to get to the less easy to access vsvs Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted December 1, 2020 Share Posted December 1, 2020 Stick it in TTC mode, takes 5 minutes, if you get full boost its a VSV, if not, look elsewhere Quote Link to comment Share on other sites More sharing options...
raddys Posted December 2, 2020 Author Share Posted December 2, 2020 Its already in ttc mode, hence the ecu next Quote Link to comment Share on other sites More sharing options...
Iky Posted December 3, 2020 Share Posted December 3, 2020 You could try opening up the ecu and just let it dry if it's full of moisture. Quote Link to comment Share on other sites More sharing options...
raddys Posted December 3, 2020 Author Share Posted December 3, 2020 No problems its all sorted now. Turns out the 1st garage i went to had ago at changing it from parallel to sequential mode and in the process completely fucked up the vsv order which in turn caused all sorts of problems. The new garage downloaded a complete vac lines diagram and put it all back how it should be. Cheers for the responses guys Quote Link to comment Share on other sites More sharing options...
