EPC errors/start stop errors

[Gedk66]

Hello folks,

I have a 2011 2.0 TDi bluemotion estate. It recently had front shocks replaced along with two rear tyres at ATS near me. A week later all sorts of warning lights have come on including 'start stop error', 'ABS', 'tyre pressure', also the drivers seat belt alarm. More than a coincidence I'm thinking but the guys at ATS deny any wrong doing. The warning lights are intermittent, in that they are not on constantly, but come and go. Obviously, when they're off, the start stop function works fine. I've checked all four tyres and the pressure is spot on, so although that warning comes on, it's incorrect.

Any help, please?

TIA, Ged.
