I have a Skoda Octavia mrk3 65 plate 2016.

1.6 TDI 81kw 5E.

Car is running like a tractor, couple of garages have looked at the car and said need new engine.

So my question is, our engine code is CXXB

And after some research I’ve seen that we could swap it out for an engine from a vw golf mrk7.

1. Has anyone successfully done this?

2. Octavia engine code says CXXB 5E / Golf says CXXB 5G , what does the 5E/5G mean? Would it cause problems?

Garage is suggesting a golf engine as a lot of Skoda Octavia’s have been taxis and might not be a great choice.

3. Added a video of car incase anyone’s had this issue?

I had a guy on fb marketplace yesterday trying sell me an engine and gave me false info on reg engine came out of, total scammer. If I hadn’t questioned him, I could have easily been out of pocket to the tune of £1,800.

Any help would be greatly appreciated, female in need of honest help.

Cheers

Meant to add my car is our family car used daily , done approx 110k miles.

It all really depends on what has happened to the engine. That noise could be a dropped valve, a loss of an injector - or the crank has suffered failure. I agree it sounds horrendous, but as a first port of call, a scan needs to be done to the car and some proper diagnosis. I think its important to figure out what you'll budget will be. Replacement engines can be sourced, but is the cost more/less that the vehicle is worth? The death knell will be if the car has either suffered oil starvation / poor maintainace, spune a journal bearing and its ended up scoring the cylinder or a valve has failed and has scored the cylinder lining.

5E is refering the fact this is a MK3 Octavia. You get 5E5 for hatchback/limosine or 5E9 for estate/combi.

You are based in Scotland (according to your profile); I suggest that you find a good VAG specialist garage to get to the bottom of the problem. My personal recommendation is Autohaus in Edinburgh who are fantastic.

Agreed - have the garages said what is wrong, to explain why they've concluded it's new engine time?

A lot can be done to repair an existing engine. Sometimes it's better the devil you know.

On the bright side, CXXB is quite common and fitted to a range of VAG vehicles. I'd think going for one from a Golf (or maybe a Seat) is a good shout in order to avoid taxi's or van engines, but that's never any guarantee as to a replacement engine's overall condition. Getting one with a known background, service history, and warranty is probably the best you can aim for.
