Egr valve on peugeot tepee 58 plate

If you have found the fuse box then you can visually identify it. If you take a new fuse you will see a small piece of metal connected in a U shape. When the metal is broken then it is bad. It may be accompanied by a slight burn mark as well.

fuse box under bonnet replace with the same one that's blown

Most are behind or below glove box.

EGR valve blow-out can be caused by a clogged catalytic converter. A clogged cat. converter will cause pressure to back up in the engine. A test to perform is remove the front oxygen sensor from the exhaust to see if the engine runs better. Removing the oxygen sensor will relieve the pressure if, in fact the cat. converter is clogged. Another cause for EGR blow-out could be that the timing has jumped.The timing can be checked to diagnose this issue.

Start over & actually ask a question in some detail

If you can not diagnose take to a repair shop

it is better to check the fault codes in the engine calculator and sure the ABS.
can you tell me why you replaced the EGR valve

Hi this could be many things.

Most likely it will be the air mass sensor, the lambda sensor, or the EGR valve, although if the EGR valve has gone you will notice a big loss in power.
You will have to get the car put on a code reader to be sure.
