Sudden power loss under acceleration
(1/1)
TheBALDpuma:
Hi all, looking for some thoughts.
I was just re joining the A1 after the services and accelerating relatively hard on the slip road when at about 60mph it felt like I hit a sudden limiter and just lost all power. It then wouldn't accelerate much past 60, and if I let the speed drop it was really really slow to pick the speed back up. Felt like a sudden limp mode but there were no warning lights and otherwise engine running fine.
I pulled over, turned the engine off and on again a couple of times and drives off and all is fine. Power back to normal. Running fine. Did about another 100 miles no issues.
Any thoughts what's going on?
GVK:
Was going to suggest you had a boost hose come off , but a restart wouldn't solve that!
Any warning lights on when it faulted?
TheBALDpuma:
No warning lights at any point
Chatgpt has come up with a few options, from reading the options I'm thinking the N75 boost control solenoid could be to blame - anyone got any experience?
GVK:
Could be that, I know they are a mission to fit on the mk5, buried round the back of the engine under the turbo.
I know you didn't have any warning lights on but can you check if any codes stored such as underboost etc?
TheBALDpuma:
Hey that's probably a good shout - will have to go to my local mechanic
