I have just replaced a cracked header tank on my 2000 99 Carrera, with only a few scuffed knuckles for my trouble, however I had to disconnect 2 fuel lines to make the tank easier to fit/remove.

Disconnecting the battery may remove the cel but you will need to go through the process afterwards of " After re-connecting battery" as per the drivers handbook

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I have just replaced a cracked header tank on my 2000 99 Carrera, with only a few scuffed knuckles for my trouble, however I had to disconnect 2 fuel lines to make the tank easier to fit/remove. Since rebuliding, the engine is noticeably lumpy and the engine check light has come on! [s1][&o] Has anyone got any ideas if this is a simple fix or will I need to visit my local indie for assistance??? Thanks Damien

POST 2Original post

I would start by looking for a disconnected vacuum pipe. There is a small one from the throttle body which runs around that area of the compartment. If it is disconnected, it gives you the symptoms you are experiencing. If it is a Tiptronic, there is another small vacuum pipe which runs to the ATF cooler valve, and that runs behind the alternator, so check that too.

POST 3 / ORIGINAL POSTEROriginal post

Thanks Richard. I have had a look but I can't see anything disconnected. Any more ideas???

Hi Damian Disconnecting the battery may remove the cel but you will need to go through the process afterwards of " After re-connecting battery" as per the drivers handbook If you search on this forum there's a link I think explaining a sequence to go through If your based anywhere near lancs I have a scanner I can turn it off for you hope this helps cheers steve
