Got flexi pipe replaced on front of exhaust as it was leaking, had new flexi welded in at power flow dealer. Now car goes into limp mode after driving about a mile or so any ideas, have also just stripped and cleaned egr valve and fitted modded gasket as egr was clogged up and car started chugging real bad. So any ideas on limp mode and possible other power loss probs/fixes

You need to get the codes read on your car....

i'd be tempted to say recheck your egr adn boost sensor

but since you already had dpf problem then maybe its regenerating

try taking it for a good run but keep the revs over 2500 for about 30 minutes
