Frustrated with glitches on 2004 Bentley GT

Hello chaps, Am I just unlucky, or do other people suffer endless glitches on their cars. I've only had mine since February ( a 30.000 miler, with ten Bentley stamps in the book), and have had to have new power steering hoses + pump, and a new air con hose. Now the dash has lit up like Christmas, with a parking brake fault, an engine management fault, and a traction control fault. The tyre pessure monitors, and heated rear screen have never worked, since I've owned it,and won't be fixed during my ownership I have had the car on a diagnostic, and these faults are for real. I've booked the car into a specialist to fix them, at God knows what expense, but am beginning to feel worried every time I drive it now, that something catastrophic will happen. I didn't buy this car with my head, as owning a Bentley or Royce, has been a dream for years, but I didn't expect something purporting to be a top end motor car to be so poorly constructed.
Regards. Tim.

Good Lord! If no one is able to fix some of these cars, I can see what looks like an ostensibly cracking car visually, will be in essence, no more than scrap.
What should one do? indeed. I'll give it a year. If nothing improves, at least I have lived the dream (?), and will move on, much the wiser.

Have you replaced the battery (or batteries)? What you describe sounds incredibly common in multiplexed cars with weakening batteries. The same thing happened in my '99 Jag when the battery was starting to go. And by "starting to go" I do not mean that it won't crank the car to start it. Most of these cars can be started on a battery that's not got enough residual power to allow all the electronics to power up correctly, thus triggering a raft of spurious warnings, most frequently when you first start the car.

Also, you've "fallen" (I can't think of a less loaded term) for the old low mileage bit. A 10-year old car with 30K miles on it has been little more than mobile sculpture, and that's sheer **** on the vast majority of mechanical systems that require regular use to maintain optimum health.

Mind you, I'm not defending Bentley, as both RR and Bentley lived on the respective brands' cachet long past the time when they should have been far more concerned about making vehicles that are up to the reliability standards expected from top-end luxury cars.

Hello Brian, I have recently replaced, only the smaller of the batteries (right hand side as you look at the boot). I will buy another for the other side ASAP, as it is a possible "cheap" fix. Several people have now told me that a well maintained, ten year old, 70 or 80 thousand mile car, used on motorways would have been a better option. As always, one lives and learns. I'm on a steep and costly learning curve at the moment. Thanks for the reply.

Regards. Tim.

It would not shock me one bit if the new battery causes a number of the warnings you're getting to disappear. If that turns out to be the case it might be very helpful if you could document which ones did go away.

I feel for you and your situation. When you're dealing with the really recent (less than 15 years old) Rolls-Royce and Bentley cars there's very little in the way of "collective wisdom" out there about them. Most are in the hands of their first or second owners and being serviced by dealers. It's only once enough of these cars become "old enough" to begin entering the community of committed DIY-ers by their price coming down sufficiently that you start to get that wisdom being created and collected. You're at the leading edge of that transition.

A bit late here but, in case it's helpful to future searchers...I spend much of my week dealing with "under voltage" issues that, as @guyslp says, cause major bother in modern vehicles running networked systems.
If people find themselves in a similar situation, my advice would be to obtain a full system scan (will need to be a decent tool) and note the nature of the stored faults. "under voltage", "voltage too low", "power supply" faults can all be flagged during low voltage upon cranking (even if your bentley starts) and will be given "permanent" status and will required clearing via diagnostic tools.
So first the ensure you'd got battery voltage (both mains and starter batteries) nice and high, clear faults and reassess.

If you require technical assistance please PM your vehicle's last 5 of the VIN.

Hi Tim,
How did you get on with the continental ? Did things settle down or was it a money pit? I'm thinking of selling my 1990 mulsanne for one.

Hi Quarryman, you are stepping up into a completely different league when it comes to problems.

If you are not completely happy with Christmas decorations lighting up your dashboard and can happily drive with warnings showing - be very wary. Mechanicals are a RPITA as well so self repair is tricky.

There is a very good reason that great looking GTs can be bought at such a ridiculously low price.

Fantastic cars to drive - just wouldn't want to pay the bills on one.

Regards, Paul Yorke.

Hi Paul, Thanks for that, I've been doing a lot of reading about the GT's. Fantastic car but the only thing I've been reading is people saying about the repair bills. I think a lot of people will come here and say about breakdowns and repairs but no one comes on and says fantastic car runs like a dream,surely they cant all be that bad? Most things I've read are the electronics not mechanical which are at fault.I'm still 50/50 whether to buy one, as you say they are affordable to buy its the upkeep of them. Think Positive
