Changing fuel filter

Skuxx

The fuel filter in my golf hasn't been changed since I got the car a year ago, about 20,000 miles later. I decided I'm going to do it myself as I do all the other servicing on the car myself but I'm worried about bleeding the engine afterwards. The car is a '01 mk4 tdi golf.

Any help would be much appreciated!!

Your engine isn't common rail so requires no bleeding, just start it and let it idle for a moment before you rev/drive it.

Hi Alan,make sure and fill the new fuel filter with fuel first.Otherwise you might run unto problems !

On my allroad, the fuel filter sits at the rear of the engine bay. I disconnect the pipes, remove the old filter and refit the new one. Just before I reconnect the pipes again, I have a small funnel and fill it up with diesel.

There's a very slight hesitation when I start it first time after changing the filter, but after that it's fine.

You would probably get it started after a few turns if you didn't fill it with fuel, but it could be risky if you're battery is on it's way out.

What way is the common rail different. I changed it on my 08 Passat at the weekend and I also emptied the cannister. I put it back together and fired it up. I could hear a squirting noise for a few seconds..

Common rail diesel systems operate at a vastly higher pressure then PD or standard injector pump systems so when you depressurise the system by removing the filter it can take an age to build the pressure back up, in most cases you would run the battery flat trying to pressurise the system by just turning the key.

With PD/injector pump systems the pressure is low so pressure is built up in a couple of turns of the key at most. VAG PD engines usually start on the first turn.

These have a lift pump in them. Just turn the ignition on and off a few times every 3 seconds making sure the exit pipe from the filter is off. Then when fuel starts to come out of it hook back on the pipe and continue to prime it for a few seconds after that. It should start straight away.

Amazing you would think the newer engine would be easier to prime.

No they don't.

The OP's car is a 01 so has a injector pump. It was the PD's from 02 on that got the electric pump in the tank.

Personally I normally fill the filter. Saves all that winding on the starter with fuel pump running dry

Oh right it was only 02 onwards they got unit injectors with the lift pump. Didn't know that.
I probably would fill it just like I used to do with transits but we don't keep any diesel in stock anymore.

there was some 115bhp pd engines released in 01
