Bosch K Jetronic Fuel Distributor - Quick Look

Whilst I've got it out of the car I thought I'd give you a quick look at a fuel distributor from a Bosch KE Jetronic or CIS injection system. Popular with Porsche, Mercedes and VW/Audi in the 80s and early 90s before EFi became more ubiquitous.

This setup is out of my 1994 Audi 80 2.3e that has the NG engine.

Here's a link to the Mercedes Source video about cleaning CIS/KJet injectors:

I'm so glad that electronic fuel injection superseded this system. It's far simpler and straightforward to deal with

Just as an aside if a K-Jetronic car seems to be suffering from fuel starvation be aware that at least in some of these there's tiny fuel filter on the main inlet. If this gets blocked then you're going no where fast. I was told by a Audi dealer in the UK that it was meant to be removed at the first service after delivery e.g. 1000 miles but they never are.. Mine lasted until 135000 miles until nearly coming to a halt on the UK M6. This particular car was a 2004 Audi Coupe 5E and after establishing it was a fuel issue it was pretty soon obvious as soon as I began to disassemble the system. I can't remember if I actually removed it just pushed the innards out with a screwdriver but problem solved and it ran for another miles before getting rear-ended and written off.

Great video! I just recently got myself a Volvo 240 Turbo with K-jetronic fuel injection. I think it's a really interestning fuel injection system, even though there are many parts that can break down.

I'm glad you got a good understanding of the system...now we have a clue as well. :)

My 1978 5-cyl Audi 100 5E has sat for 26 years. I believe everything has to be taken apart and inspected. Even if the fuel quality in 1995 was better than now 😃

Not many people know this but the CIS system is the most profitable thing Bosch ever developed.

Hubnut is now NZ. Maybe he might come and visit you.

Buena explicación quisiéramos saber la instalación y desmontaje de los inyectores

[BleuJurassic]

hydraulic hose works well for high pressure systems take the the ends and they can make them up for you

[paulmayou]

hi mate its a simple thing really compared to todays cars

[ErskHansen]

My Volvo 740 1987 with K-jetronic didn't start. This will help me to find out the reason ...

[zilizopendwa]

Thanks for the informative video, is it possible to replace a k-jetronic directly with the ke-jetronic fd system if you k-jet is faulty?

[andrewdrevdahl]

My system pressure is good but when I turn the valve on it drops for a second then climbs right to system pressure cold with electric connector to warm up regulator un plugged tks for any help . I think I will have to repair war but want to be sure

How do you adjust the height of the plate? I took away the plate but could not figure it out (KE-Jetronic Audi 100 2.0 E 1990)

[flyboyfs]

Hi, i am interested on the ford rs turbo one, they have an extra pressure valve and a 3 wire black, plug. Can I use normal k tronic one non turbo on a turbo set up?

[alexr]

my Audi b3 coupe broke down today new fuel pump and filter fitted but still broke down revs cut to idle !! as if fuel pump not working but it is !!

[mornemarconi]

Great video. Got mk2 jetta cli 16 valve kjetronic myself.
My car didnt want to idle.
However if i manualy work the sensor plate and override start relay the injectors spray.
I check for fire and firing order. All good. Fuel supply at the onjectors all good. No fuel coming from injector lines.
When does fuel come from injector lines if all are good on the system?
