Auto gearbox 206 '03

[Debs29]

Hello, need some advice please on my 03 206. It has an automatic gearbox and for several months now I have been hearing a hissing noise which is definitely coming from the gear selector area. The noise would disappear after the brake was applied but I'm noticing now that it stays on most of the time. It isn't consistent, i.e. some days I dont hear it at all, but it's happening more often now. Today I noticed whilst driving along that the snow and sports icon kept coming on. Also I have problems with the gears not changing down sometimes and the only way round the problem is to turn the engine off and try again. Any advice would be appreciated.

Welcome to the forum.

The automatic transmission unit is equipped with a fluid wear sensor to inform the driver when the fluid needs renewing (the ECU flashes the Sport and Snow mode indicator lights when fluid renewal is necessary). The sensor should be reset after the transmission unit is drained and refilled with new fluid.

If I were you I would book your car in promptly to get this work done. There is no point in risking damage to the automatic transmission unit as replacement of that would be very expensive indeed.

Let us know how you get on, and how much it costs please, for the benefit of other members.

Thankyou for prompt response, I'll try to do that today.

I've just been to my local garage and they "scanned" the car and said it's a pressure regulator that needs replacing. Unfortunately they're not able to do it and so needs to be booked in at a transmission place. They've quoted £400 plus Vat.

OK. No doubt the transmission specialist will carry out their own diagnosis to confirm that the garage is right, before you commission the repair work. The pressure regulation solenoid valves are a fairly common problem.

Sorry to hear about the big bill just before Christmas.

I guess they'll renew your transmission fluid at the same time as carrying out essential repairs.

Hopefully the car will be as good as new when the work has been done.

Best wishes, Ron

I have edited my earlier post today to include a hotlink to an informative webpage.

Thank you for that. To be honest I'm totally confused as to what I've just paid £430 for. Receipt said pressure reg/solenoids. Went there with three issues, firstly the Sports/Snow icon flashing, only the once. I mentioned the difficulty sometimes in gears changing down, plus this air/hissing noise from gear selector area. Collected car yesterday, drove away and the hissing noise was still there - he did say it was a servo/brake issue and although I havent driven very far yet, I can't say there was any difference in the gears. Will try to give it a good run today and see. The other issue now is that although I had it serviced in October, the spanner symbol is now only showing 2 squares whereas before it was full seven?

The hissing noise from the brake servo is fairly common. The brake servo is situated just in front of the passengers knees, in the engine compartment. Is the hissing noise coming from there? If so, unless your braking efficiency is affected I would live with it.

As for the gearbox issue, I still stand by my original thoughts - albeit at a distance without seeing the car.

The garage (was it a Peugeot garage, because it doesn't sound like it?) told you that the problem was something else, and I mentioned that I would expect the automatic transmission specialist to confirm the diagnosis before authorising the work. If they changed the solenoids then I think they will have updated the software. I wonder whether this could have affected your service spanners.

Did they renew the transmission fluid or not? If not, why not?

If you notice no improvement then perhaps the garage's diagnosis was incorrect, which is why I mentioned that the transmission specialist ought to confirm it first.

I am beginning to wonder if they have given value for money too.

No, the garage was not a Peugeot garage. When I first phoned them to explain about the flashing sports/snow light they said bring it up and we'll scan it. I did that and three minutes and £30 later they explained what the result was. They called the transmission garage and told them and then explained to me about the diagnosis and cost. I didnt think I should have to pay out yet again to have it scanned. Stupid in hindsight I suppose. Having said all that, the car does appear to be running better, i.e. gear changing etc. I was wrong about where the hissing noise was coming from, you are right in saying about the passengers knee area, but would it be right for it to be so noisy that I have to turn up the radio and can still hear it. But no, it doesnt appear to be affecting the performance of the brakes. As for the spanners (of which there are 6), it has increased to five showing now, so that's a good improvement.

I would just like to thank you very much for your guidance and comments in this matter.

I just hope they changed the transmission fluid. I'd get them to confirm that they did.

As for the hissing servo, here's a link to another thread where someone else had the same problem:

If it is really bothering you why not get it done. It'll cost you a couple of hundred pounds or so. If the brake fluid hasn't been renewed in the last couple of years I'd get that done at the same time.

I'm glad the gear changes are getting better. I think the car's electronic brain has to relearn your style of driving, so it should improve further as you continue to use it.

Pleased to be of help. Wish everyone was as nice as you.
