My Dad has an E Reg Jetta 1.6 now up to 130,000. It's been an excellent car. However it has developed a problem and I'd be grateful for any help.
The heater is hot for the first few miles driven but once the car gets to normal operating temperature the heater blows only cold air. He has changed the thermostat and drained and flushed the cooling system (including flushing the heater matrix seperately). Still hot air for only the first few miles.
Any ideas as to what to do next, as ever all help greatly appreciated.
Thanks,
Andy.

Been covered before. There was a worldwide recall for this because heater matrixes were blowing and if this happened in freezing cold weather the car's windows immediately steamed up (imagine the consequence on the autobahn). First fix was a blow off valve. Second fix was a new heater matrix, even on cars ten years old. But someone else in The Backroom recently pointed out that this recall programme was now over. By the way, does anyone want an 85C Jetta GT with all the heater recall work done and 129,500 miles (I got it wrong in the classifieds) for £100? Still taxed and tested too. And with petrol in the tank.

BTW HJ, someone on a GTI mailing list I am on said they rung round VW dealers and still managed to get it done FOC.

I am working @ VW Dealers, recall still applies, as do any outstanding recalls on VW Range. If this car has had modified valves fitted,they may well have failed or be blocked.

Hi Mark S,
sorry for being off topic, but we would be interested to hear if you, or any of your colleagues, have any comments on cabmanuk's "running out of oil" thread at www.honestjohn.co.uk/forum/post/index.htm?f=4&t=80...5
We cannot explain why all the exhaust tappets are damaged in this way. Any ideas?
thanks in advance,
CMark

Just had the quickest of reads...what a can of worms! Here in VW land, we don't have any common/specific engine problems that keep happening.Engines as a unit are usually robust, the only problems being when a head has new valves fitted after a cam belt failure..due to impact damage the seats & guides become distorted & valve collets fall out, or valve stem shears. The damage can then be ingested & throughly distributed throughout engine, ending up miles away from where it occured: sump, another cylinder, bearing shells etc. In all cases of bent valves we always replace the head complete as history has taught that more problems await if this is not done. Sorry I can't be more specific.

Had the same problem with mine about a year ago. Went to local VW dealer and bought the part (just explained the problem and they knew what I needed), basically the valves to control the flow and return to the heater. Don't remember the exact cost but I am sure it was less than £20. If you can use a screwdriver you can change them in less than 1 hour. Why bother trying to find a dealer who will honour the recall.

I have the same problem on my Pug 405.
Heat comes from the heater (almost too hot) whilst the engine is warming up. Once the engine is warm you can only get heat on the "Hot" setting.
I wondered if it was an airlock or partial blockage so that water pressure through the heater is only sufficient with the engine thermostat closed.
No coolant loss or any other visible symptoms.

405 has a very complex method to top-up and bleed the cooling system. I don't recall the method but the Haynes manual should cover it? Quite easy to get an air lock somewhere in the system though.

Hmmmm ....
The coolant was changed by the main dealers at the previous service, they should have got it right, but you never know!
|
Just to let people know, we changed the bypass valve on the jetta (£39) and everything hunky-dory. Thanks for the help.
Andy.

Seeing ajsdoc's reply, has the 405 got a bypass valve, I wonder?
