Are you certain that you are referencing the vacuum leak above the transmission? When I removed the driver's side pre-cat, I had a very careful look into the issue and could not see any way to access the junction without removing the engine. I even explored coming in from the top under the shifter assembly (i.e. cutting through the floor). Ultimately, we all concluded this would be even more work than removing the engine/transmission. If your guy has a way to do this without the engine coming out, all of us would VERY much like to know the procedure.

 

He is replacing the vacuum lines that crack and do not allow the waste gates to open and throw the engine code. My car would lose power randomly. I went to Bentley and was quotes 10k for this job. Here is my car on a lift, he said all you need to do is take down the plastic above the tires to get in there. He said Bentley then charges for engine drop that never happens.

here is a picture of my car getting the lines changed i will have more soon.

 

Maybe they changed the location of the hose from the older 2004 to 20?? design with the newer models?

 

Mine is a 2009-2010 model the lines warp around the engine, it was melted not even cracked, i will ask him more info on years.

forgot to add dealer also told me i need new turbos 17k, tech said that's a lie all i need is that line.

 

Holy !!!!! Am glad there are some great independent service guys near me. So tell us, who is the dealer that said this as we should all know to keep things in mind in the future.

 

I understood from my Indy that as from the 2008 MY they changed the design and that you don't need to take the engine out to replace the line that goes above the transmission.

if he is right, and knowing him I believe he is, it is another proof that the original design was flawed.

having said that, Bentley Mc still insists in taking the engine out in case of a leak above the transmission....
who is right???

 

Spoke to my guy he said they are the same on all bentley continental I'm getting them replaced with out engine drop. Lines alone $1500 that's with discount from dealer. 10-12 hours worth of work?

 

New lines now come with heat shields around them. This means they recognize the issue of them melting from heat.

 

Thanks for keeping us up to date. Will your guy provide insight into his procedure? I am very curious to see how he gets to the junction at the top of the transmission. Pictures would be of huge benefit.

 

You have to take out the steering rack.

 

No, taking out the steering rack doesn't allow you to replace the line above the transmission.
by taking out the steering rack you can replace one of the, various, vacuum line but by no means you can reach the connection above the transmission.

I don't remember the price of the lines but I don't think is even close to $1500, they are cheaper than that. you should check with Flying Spares.

 

 

hehe

 

Thank you for the pics. When you originally discovered the vacuum leak (I am assuming a smoke test), where was the leak? Did you replace the vacuum line over the transmission?

 

Am not home to give exact part#, yet the vacuum leak above the tranny on the 07 GTC was a single hose that was $300 (probably a $75 hose they overcharge you for at 'Bentley pricing' of course).
