Found this excellent video of the GT clearing showing the hissing from a smoke test and after video with replacement metal vac lines.

Indy in this video commented vac lines are a common problem from 2004 to early 2006 but some of our 2007 members also have this problem. Did Bentley ever resolve this problem before the new model came out?

Interesting videos...

After viewing both, I found the Part 1 video segment, which shows the vacuum pump location.

Well, I hope that none of you have this problem.
The price at the main dealer to fix it was 3,554. Although that did include a new exhaust gas sensor, new auxiliary pulley belt and a new paddle shift control unit.
That was on top of the 1,895 I paid the week previously for an 8 year service which included two new cam sensors, a new door mirror and a new boot release button plus MOT test.

All in all, a costly few days. Unfortunately, the paddle shift still has the same fault, so I guess I didn't need a new 354 control unit. The main dealer now reckons it may be a wiring problem. I had already told them that it was intermittent so am surprised they didn't check the wiring first. He said the original control unit was faulty anyway so I have no comeback. As I needed the car for a trip away I had to take it as it is.

It's a pity that the Indy was too busy to repair my car at the time, it would have saved me a lot of cash. I think he will get my full patronage from now on though.

Les.

Tbh the charge for dealer repair isn't too bad! Considering how many parts have to be removed they could charge you 5G easily.

Indication(s) of problem

As I own an '07 GTC - this plastic vac line issue concerns me. Would you please state your initial observation(s) that a problem existed which would
require a repair. Thank you.

Loss of power... Engine stumbles... engine light turns on. I noticed a loss in power when first getting the GTC and seems it took a bit longer for the light/problem to truly rear their ugly head. If I had not had a previous GT, one would probably not notice the loss of power before things get too bad and thus stumble/engine light.


Have a smoke test done on the car.

And for us Brits, it's the passenger door. The pump is behind the left front wing/fender.

I only became aware of the problem when the Indy doing the service found it.
I'm glad Bentley seem to have addressed the problem on later cars.

Parts to be replaced?

Does anyone have part numbers that needs to be replaced?

So only 1 line not 2 or 3? I have 06 GT. Just spoke to dealer in the area, he said that 3W1612041S fits 08+ GT's and he hasn't sold any this year, however the one that fits my car is 3W1612041M and list is $505.33 and he has sold 3 this year. Any idea if there is any aftermarket hoses?

No idea, yet what I posted is the hose they changed on my receipt for an 07 GTC.
