VW Polo warning lights

So the car is a 61 plate and only done c 60k miles. 3 warning lights have come on. Engine, EPC and electronic stabilising system

No doubt all linked. I am hoping it’s a simple reset or sensor replacement. However garage no doubt motivated to replace everything at great cost!

Any ideas?

I would check and clean your MAFF sensor. EPC points to a throttling issue, which would explain both EML and ESP lights
 
Had this on Wed followed by total loss of power and a cost to the hard shoulder. 36 hours later and garage phones to say it’s cam belt so hopefully yours isn’t as bad.
 
Given the variety of answers, I’d definitely pay to have the codes read before I started replacing parts, particularly at VW prices.
 
Likely abs sensor failure, get codes to identify which one. Relatively simple replacement if it is.
 
The first thing to do is rule out the battery. Charge it up or if it's obviously goosed, replace it. Then, assuming that doesn't fix it, get the codes read by someone competent and you should find out what the issue is.

Before having a spend. Get on Reddit or a Polo owners forum.

You may find its a common issue and easily fixed. There are plenty of helpful people on them.

What exact model, spec, engine is it?
 
Could be a voltage drop due to the battery

I recently had an "ad blue initialisation failure" [or similar] come up on my dashboard and vehicle refused to start. It turns out a low battery caused that. AA man said vehicle will not start unless all computers are 100% happy.

I.e. solenoid did not kick because preceding logic steps failed. On older cars, a tell tale stutter from the solenoid or sluggish turnover would be your diagnostic for flat battery. In my case, headlights were bright, dash looked like a christmas tree, but nary a peep from solenoid.

If the battery doesn’t produce 12 - 14volts the reduced voltage produced will be seen as a drop in power to or from various components and trigger the ECU to record faults.
Get a diagnostic tool and a multi meter and learn how to use them before you replace expensive parts based solely on dashboard warning lights.
 
Thanks all

Odd one. Started it up again today. No lights - they only come on when driving. So did about 10 miles in it, nothing all fine. Must have somehow reset itself

You need to get the error codes read or read them yourself with an OBD11 scanner as already mentioned. Your fault is intermittent and could re-occur at any time. ABS sensors are notorious for throwing up all sorts of errors as much of the car's systems rely on input from them. However, if an ABS sensor is at fault then usually the ABS light will be on along with the other warning lights so your problem may be something else.
