Hello all, please can you help?

I have a 2017 1.2 TSI Yeti Outdoor and suddenly neither front nor rear pumps are spraying. Yes, there is a full reservoir of fluid, and yes, I can hear pump noises when I apply the relevant commands. Please can someone suggest what might be going on and what to do to fix it, in language a non-mechanic can understand?

Also, at random points the EPC light comes on. I can restart the car and it goes out again. Only sometimes does the "check engine" light also come on, then the car really does limp. But, pull over and turn car off and on again and it goes. What's all this about? Again, any help in language a moron can understand would be greatly appreciated.

I do have affection for this car, but after 2 years and 15k miles, it has suddenly become a money pit. Are these issues portents of further trouble? My past cars were Land Rover Mark 2 Discovery's, which became a game of bingo as I checked off the list of known faults until I learnt my lesson (ULEZ sped up the proceedings too).

Any help that you can offer would be wonderful. Please let me reiterate that I don't speak the lingo. But perhaps one day I might be able to reciprocate with sage advice for someone else?

Thanks in advance.

Re EPC light, get the fault codes read if any, see what they are, are there Mis-fire codes logged?

When were the spark plugs replaced or looked at?

Check nearer the Windscreen washer, is the liquid being pumped out.

Are the pipes / nozzles clogged, jelly formed in them.

A bad mix of washer fluids / bacteria.

Yes, and also just a washer pipe disconnected or a cut and the system loose pressure and no fluid will be sprayed.

Thanks Ootohere and Jack25 for offering help so quickly and in words I understand!

I'll run the diagnosticator-tron later and report back with the gobbledegook codes.

As for windscreen jets, nothing looks awry, and both the front & rear stopped at the same time so maybe a hose is to blame. Are they easily traceable, i.e.: nothing has to be dismantled or put on a ramp to investigate?

I really do appreciate getting useful responses so quickly. I thought I might have to give it a week. Thanks.

No problem, 

For the fault lights, does the car have a regular idle? i have some suggestions:

• a faulty coil 

• worn sparkplug 

• faulty coil connector 

• a rough idle could be a dirty throttle body

did you have done some maintenance lately? or like a turbocharger replacement? (in another yeti post a 1.2 tsi from 2013 had a turbo replacement without calibration and it was over boosting).

For the washer fluid: the reservoir can be seen removing the front right wheel and inner fender liner. There you can see the pump and the beginning of the pipes. There is some option here           

•  The reservoir pump is clogged but working, the poit where it sucks up the fluid id very small

• a loose pipe could be under the windshield wiper. There is a t-junction for the two nozzles. 

• the rear wiper tube is broken inside the plastic trim on the floor inside the car. It runs alongside the bottom part of the door. If the fluid is leaking there, that's a big problem because it is full of wires that area, you can try to see if the carpet is wet. Generally, the pipe is in the left side of the car. To be sure try both side or inspect the tailgate for fluid tacks.

• also could be related to something loose in the headlight washer system
