I'm surprised to hear that his employer purchased and issued a diesel car for him. I had understood that diesel vehicles had some kind of a tax or other issue, that made them a little less desirable in GRT Britain.
It looks like the repairs are on his dime.

There are still quite a lot of new diesels being sold over here, especially for those who travel long distances like Wayne does as he travels all over the country... Cops are always putting gasoline in their diesel cars & vans, it's a big joke in the media as there are always cop cars & vans off the road awaiting repairs after wrong fuel fill ups..

Bright Boy here had a 1976 Oldsmobile Cutlass Supreme Brougham, w/a 350 V-8. It was the most popular car in America 1975-77, they must have sold 3 gazillion of 'em. Anyhow, 1975-79 were my College years, I live in Tennessee, but went to school in Richmond, Virginia, roughly 400 miles away. Was tootlin' back to school after Spring Break, '77, needed some gas & a "Hit the Head" break, so I pulled off I-81 in Roanoke, Virginia, stuck the nozzle in the tank,went & did my business, came back to pay the gas station guy, he sez, you owe me $15... I sez, No, I used that Cheap Gas... He sez, "Well, son, you just put 7 gallons of #2 Diesel in yer car. Gulp. Now, there are times when even the meanest baddest dude alive wants his Mama, & THIS was one of them times for Moi. Will it hurt my car ? I squeaked .. Well, Shit-Fer-Brains, it won't hurt it, but it'll beat & bang, smoke, run rough, but it shouldn't hurt it...Well, here I go, on to Richmond. I went 70, prayed there weren't any cops-Virginia took "55 MPH" VERY Seriously, 'specially for out of state "Furriners"...I had the A/C on "Deep Freeze" had the radio as loud as I could stand, ANYTHING to run that Weasel juice outta my car. And yeah, it beat, banged, run rough, smoked like a freight train, the whole 9 yards. I'd stop every 25 miles or so & would top off w/"High Test' gas, as we had disconnected all the fed BS anti-pollution junk, I could run any gas I wanted. I finally got back to school, I shut 'er off, it just set there, kept running, & shook like a Baptist preacher at a Tent Revival. Well, I guess you'll eventually quit, I said to myself. Richmond was a small school, they claimed 5K students, but that was with all the law school, grad students, etc. At the part I was in there were about 1500 guys-Richmond College- and 1000gals-Westhampton College. Most good gossip took a day or so to make the rounds, I think my ordeal took about 15 minutes. People I didn't even know were coming up to me, pointing & laughing-YOU'RE the Arsewhole who put Diesel in his Gas car, aren't you ?!? What an Eediot ! Ahahahahaha...!! I paid dearly. And my dear, loving, trustworthy Fraternity brothers-Shit, they rode me worse of all... Long term, both me & my Oldsmobubble survived. You CAN put diesel in a gas car, & it WILL run, but I really CAN'T recommend doing it. Going the OTHER way around-Gas in a diesel-I don't think THAT would work at all.

I have been telling that story for nigh on for 50 years-Gulp- now, & have gotten LOTS of laughs & grins over the years... So, even if I might have suffered a bit from it, the enjoyment it has brought others-And ME- has been way more than worth what ever trouble I suffered...

It depends on how much diesel vs. gas is in the tank. Mostly gas on an older diesel (like my 91 Benz)? No big deal... the car would just stop running. But if it was closer to 50/50 the engine might still run... and you'd likely burn through the prechambers or pistons. If you had just a little gas it wouldn't hurt anything - in fact in the 70s MB suggested mixing some gas into the fuel tank to help prevent fuel gelling at very cold temps. The inline fuel pump is lubricated with engine oil and is rather robust.

On a newer diesel, like our prior '12 Passat TDI, the fuel is what lubricates the 28,000 PSI high pressure pump. Adding a little gas destroys the lubricity of the fuel, and the pump will self destruct and fill the whole fuel system with metal shavings

I've read that some owners of low compression leadded gas cars will intentionally add ~1 gallon of diesel to a full tank of gas to try to keep the unleaded from damaging the valves...Twas on the interwebs so it might a been skuttlebutt.
